Abstract:

Study identified groupings of community-dwelling individuals with traumatic brain injury (TBI) in a cohort recruited in Australia, and compared groupings from the Australian cohort to groupings previously developed for a cohort from the United States (US). A total of 170 participants with TBI from Australia and 504 participants with TBI from the US were administered an extensive battery of cognitive tests and questionnaires. The cognitive tests included the Wechsler Letter-Number Sequencing and Coding subtests, the Rey Auditory Verbal Learning Test, the Trail Making Test, the Word Memory Test, and the Verbal Fluency test. Questionnaires included 9 scales from the TBI Quality-of-Life system, the Neurobehavioral Symptom Inventory, the Economic Quality of Life Scale, and the Family Assessment Device General Functioning Scale. Cluster analysis of the Australian cohort was conducted to derive a 5-group solution allowing comparison with the US data. Agreement between group assignments based on the Australian cluster analysis and reassignment of the Australian sample based on the US means was assessed using Cohen’s kappa coefficient of agreement. Results showed that agreement in classification for the 2 samples was only moderate, with 63.5 percent correctly classified and Cohen’s kappa = 0.53. A post hoc analysis placing all persons showing poor performance validity in the same group improved classification to 73 percent and Cohen’s kappa= 0.65 indicating substantial agreement.
